Description:
You wish to install software or update software in a system protected by EWF mode (Windows XP Embedded Standard). If you disable the EWF for drive C:\ using the command "ewfmgr c: -commitanddisable" without rebooting the system beforehand, in rare cases it might happen that the system no longer starts after rebooting. The following message is displayed:
"Windows could not start because the following file is missing or corrupt:
WINDOWS\SYSTEM32\CONFIG\SYSTEM..."
Cause:
The Windows Embedded Standard 2009 Installation on SIMATIC IPCs used a customized Registry entry. This Registry entry leads to the behavior described.
Remedy:
Install the attached Registry patch in order to be able to change the Registry entry. Installing the "REGFILTER_Patch.reg" Registry patch changes the Windows Registry.
Proceed as follows to install in a system protected by EWF Mode.
